I'll have to strongly disagree. There is no comparison between the clarity of the shallow rear sight notch on the fixed sight FA, and the black adjustable rear sight. Nor is there any comparison between the clarity of the front blades, particularly if the stock ramp is replaced with a patridge or undercut patridge. The stainless fixed front, or the dovetailed blue version simply do not integrate as well with the fixed rear trough, as well as the adjustable sights coordinate with each other. This is particularly obvious with the short 4 3/4" barrel lengths. This isn't just my opinion, but rather the opinion of several of us who compared shooting the fixed sight vs adjustables and round butts vs standard at the Whittington Center a few weeks ago.
The fixed sights may have their place among those who like them, but sight clarity is not their strong feature.
